[The effect of specific inducers on the biosynthesis of lytic enzymes by a strain of Streptomyces recifensis var. lyticus].

The effect of specific inductors at different stages of Streptomyces recifensis var. lyticus 2435 cultivation was studied. It is shown that introduction of killed bacterial cells into inoculum not only influences the level of accumulation of lytic enzymes by the strain S. recifensis var. lyticus 2435 but also determines the qualitative composition of the synthesized complex. The yield of bacteriological glycosidases grows with introduction of the Micrococcus lysodeikticus cells into the inoculum or of dissolvable chitin into the enzymic medium. The possibility to preserve the initial level of the lytic activity in the producer during re-inoculations by introducing the Bacillus subtilis cells into the cultivation medium has been studied.
